personally i dont know if i even feel safe leaving my dog with a kong alone, particuarly if its a strong chewer. i’ve seen some pittbulls decimate the black x-strength kongs and take off chunks of rubber that they could definitely choke on if not supervised.
That being said i use bully sticks for my dog as i dont have to worry about teeth cracks, and they are edible. i dont completely understand the logic of putting them in vicegrips, i’m not saying that is wrong i just dont understand it and would always be open to an explanation of why this was a good idea. one treat i just recently tried that i liked alot but it depends on your dog is the turkey feet from bestbullysticks.com …if you have a dog that doesnt fully chew their treats and gulps do not get these, if you want to leave your dog alone do not get them, but other then wanting to leave your dog unsupervised with one i think they fit most of your criteria and are HUGE and great for large dogs that fully chew their treats but again i cant emphasize enough they have to be supervised, but meet the rest of your criteria and are a great treat for large dogs as they are huge…I have an 85lb akita who was 35lbs at four months and over 60 at 5 months and she did great with their turkey feet, she fully consumed the whole thing and it lasted her about an hour, but with a more powerful chewer that was 100lbs+ i only give it 30 minutes, but still a good price for what you get…i also recommend bestbullysticks.com jumbo and monster bully sticks to you, they have the jumbo in stock right now, but again i do not suggest leaving your dog alone with these or any treat, even a kong….
